Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 151,048,825, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 151,048,825 | |
| -1 | -151,048,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,048,825.
Example:
1 x 151,048,825 = 151,048,825
and
-1 x -151,048,825 = 151,048,825
Notice both answers equal 151,048,825
With that explanation out of the way, let's continue. Next, we take the number 151,048,825 and divide it by 2:
151,048,825 ÷ 2 = 75,524,412.5
If the quotient is a whole number, then 2 and 75,524,412.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 151,048,825 | |
| -1 | -151,048,825 |
Now, we try dividing 151,048,825 by 3:
151,048,825 ÷ 3 = 50,349,608.3333
If the quotient is a whole number, then 3 and 50,349,608.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 151,048,825 | |
| -1 | -151,048,825 |
Let's try dividing by 4:
151,048,825 ÷ 4 = 37,762,206.25
If the quotient is a whole number, then 4 and 37,762,206.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 151,048,825 | |
| -1 | 151,048,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 293 | 425 | 1,213 | 1,465 | 4,981 | 6,065 | 7,325 | 20,621 | 24,905 | 30,325 | 103,105 | 124,525 | 355,409 | 515,525 | 1,777,045 | 6,041,953 | 8,885,225 | 30,209,765 | 151,048,825 |
| -1 | -5 | -17 | -25 | -85 | -293 | -425 | -1,213 | -1,465 | -4,981 | -6,065 | -7,325 | -20,621 | -24,905 | -30,325 | -103,105 | -124,525 | -355,409 | -515,525 | -1,777,045 | -6,041,953 | -8,885,225 | -30,209,765 | -151,048,825 |
